Assessing the feasibility, acceptability, and preliminary efficacy of a novel symptom management care delivery intervention for caregivers receiving home hospice care: The I-HoME protocol

BACKGROUND

Terminally ill patients experience high symptom burden at the end of life (EoL), even when receiving hospice care. In the U.S., family caregivers play a critical role in managing symptoms experienced by patients receiving home hospice services. Yet, most caregivers don't receive sufficient support or formal training in symptom management. Therefore, providing additional visits and education to caregivers could potentially improve outcomes for both patient and caregiver. In response, we developed the Improving Home hospice Management of End-of-life issues through technology (I-HoME) intervention, a program designed for family caregivers of home hospice patients. This paper describes the intervention, study design, and protocol used to evaluate the intervention.

METHODS

The I-HoME study is a pilot randomized controlled trial aimed at reducing patient symptom burden through weekly tele-visits and education videos to benefit the patient's family caregiver. One hundred caregivers will be randomized to hospice care with (n = 50) or without (n = 50) the I-HoME intervention. Primary outcomes include intervention feasibility (e.g., accrual, attrition, use of the intervention) and acceptability (e.g., caregivers' comfort accessing the tele-visits and satisfaction). We will also examine preliminary efficacy using validated patient symptom burden and caregiver outcome measures (i.e., burden, depression, anxiety, satisfaction).

CONCLUSION

The trial is evaluating a novel symptom management intervention that supports caregivers of patients receiving home hospice services. The intervention employs a multi-pronged approach that provides needed services at a time when close contact and support is crucial. This research could lead to advances in how care gets delivered in the home hospice setting.

Association of Baseline Frailty with Patient-Reported Outcomes in Systemic Lupus Erythematosus at 1 Year

The relationship of baseline frailty with subsequent patient-reported outcomes in systemic lupus erythematosus (SLE) remains unclear. We assessed these associations in a pilot prospective cohort study. Frailty based on the FRAIL scale and the Fried phenotype and patient-reported outcomes, namely Patient Reported Outcomes Measurement Information System computerized adaptive tests and Valued Life Activities disability, were measured at baseline and 1 year among women aged 18-70 years with SLE enrolled at a single center. Differences in Patient Reported Outcomes Measurement Information System computerized adaptive tests between frail and non-frail participants were evaluated using Wilcoxon rank sum tests, and the association of baseline frailty with self-report disability at 1 year was estimated using linear regression. Of 51 participants, 24% (FRAIL scale) and 16% (Fried phenotype) met criteria for frailty at baseline despite median age of 55.0 and 56.0 years, respectively. Women with (versus without) baseline frailty using either measure had worse 1-year Patient Reported Outcomes Measurement Information System computerized adaptive test scores across multiple domains and greater self-report disability. Baseline frailty was significantly associated with self-report disability at 1 year (FRAIL scale: parameter estimate 0.55, 95% confidence interval (CI) 0.21-0.89, p<0.01; Fried phenotype: parameter estimate 0.61, 95% CI 0.22-1.00, p<0.01), including only slight attenuation after adjustment for SLE cumulative organ damage (FRAIL scale: parameter estimate 0.45, 95% CI 0.09-0.81, p=0.02; Fried phenotype: parameter estimate 0.49, 95% CI 0.09-0.90, p=0.02). These preliminary findings support frailty as an independent risk factor for clinically relevant patient-reported outcomes, including disability onset, among women with SLE.

The relationship of caregiver self-efficacy to caregiver outcomes: a correlation and mediation analysis

OBJECTIVES

Caregivers of individuals with Alzheimer's disease and related dementias experience significant burden and adverse outcomes. Enhancing caregiver self-efficacy has the potential to mitigate these negative impacts, yet little is known about its relationship with other aspects of caregiving. This study examined the relationship between self-efficacy and outcomes; identified factors associated with self-efficacy; examined the mediating role of self-efficacy; and analyzed whether there were racial/ethnic differences.

METHODS

Data from caregivers (N = 243) were collected from the Caring for the Caregiver Network study. Participants' level of self-efficacy, depression, burden, and positive aspects of caregiving was assessed using validated measures.

RESULTS

Two self-efficacy subscales predicted caregiver depression, burden, and positive aspects of caregiving. Being White, a spouse, or having a larger social network predicted lower self-efficacy for obtaining respite. Higher income and lower preparedness predicted lower self-efficacy for controlling upsetting thoughts and responding to disruptive behaviors. Self-efficacy for controlling upsetting thoughts mediated the relationship between preparedness and depression along with the relationship between preparedness and burden. Race/ethnicity did not improve model fit.

CONCLUSION

Self-efficacy plays an important role in caregiver outcomes. These findings indicate that strategies to improve caregiver self-efficacy should be an integral component of caregiver interventions.

Do Decision Aids Benefit Patients with Chronic Musculoskeletal Pain? A Systematic Review

OBJECTIVE

To review the effect of patient decision aids for adults making treatment decisions regarding the management of chronic musculoskeletal pain.

METHODS

We performed a systematic review of randomized controlled trials of adults using patient decision aids to make treatment decisions for chronic musculoskeletal pain in the outpatient setting.

RESULTS

Of 477 records screened, 17 met the inclusion criteria. Chronic musculoskeletal pain conditions included osteoarthritis of the hip, knee, or trapeziometacarpal joint and back pain. Thirteen studies evaluated the use of a decision aid for deciding between surgical and nonsurgical management. The remaining four studies evaluated decision aids for nonsurgical treatment options. Outcomes included decision quality, pain, function, and surgery utilization. The effects of decision aids on decision-making outcomes were mixed. Comparing decision aids with usual care, all five studies that examined knowledge scores found improvement in patient knowledge. None of the four studies that evaluated satisfaction with the decision-making process found a difference with use of a decision aid. There was limited and inconsistent data on other decision-related outcomes. Of the eight studies that evaluated surgery utilization, seven found no difference in surgery rates with use of a decision aid. Five studies made comparisons between different types of decision aids, and there was no clearly superior format.

CONCLUSIONS

Decision aids may improve patients' knowledge about treatment options for chronic musculoskeletal pain but largely did not impact other outcomes. Future efforts should focus on improving the effectiveness of decision aids and incorporating nonpharmacologic and nonsurgical management options.

Linking Persistent Pain and Frailty in Older Adults

OBJECTIVE

In older adults, the impact of persistent pain goes beyond simple discomfort, often contributing to worsening functional outcomes and ultimately frailty. Frailty is a geriatric syndrome that, like persistent pain, increases in prevalence with age and is characterized by a decreased ability to adapt to common stressors such as acute illness, thereby increasing risk for multiple adverse health outcomes. Evidence supports a relationship between persistent pain and both the incidence and progression of frailty, independent of health, social, and lifestyle confounders.

DESIGN AND SETTING

In this article, we synthesize recent evidence linking persistent pain and frailty in an effort to clarify the nature of the relationship between these two commonly occurring geriatric syndromes.

SETTING

We propose an integration of the frailty phenotype model by considering the impact of persistent pain on vulnerability toward external stressors, which can ultimately contribute to frailty in older adults.

RESULTS AND CONCLUSIONS

Incorporating persistent pain into the frailty construct can help us better understand frailty and ultimately improve care for patients with, as well as those at increased risk for, pain and frailty.

Caregiver-Reported Quality Measures and Their Correlates in Home Hospice Care

Background: A majority of hospice care is delivered at home, with significant caregiver involvement. Identifying factors associated with caregiver-reported quality measures could help improve hospice care in the United States.

Objectives: To identify correlates of caregiver-reported quality measures: burden, satisfaction, and quality of end-of-life (EoL) care in home hospice care.

Design: A cross-sectional study was conducted from April 2017 through February 2018.

Setting/Subjects: A nonprofit, urban hospice organization. We recruited caregivers whose patients were discharged from home hospice care. Eligible caregiver participants had to be 18 years or older, English-speaking, and listed as a primary caregiver at the time the patient was admitted to hospice.

Measures: The (1) short version of the Burden Scale for Family Caregivers; (2) Family Satisfaction with Care; and (3) Caregiver Evaluation of the Quality of End-Of-Life Care.

Results: Caregivers (n = 391) had a mean age of 59 years and most were female (n = 297, 76.0%), children of the patient (n = 233, 59.7%), and non-Hispanic White (n = 180, 46.0%). The mean age of home hospice patients was 83 years; a majority had a non-cancer diagnosis (n = 235, 60.1%), were female (n = 250, 63.9%), and were non-Hispanic White (n = 210, 53.7%). Higher symptom scores were significantly associated with greater caregiver burden and lower satisfaction with care; but not lower quality of EoL care. Caregivers who were less comfortable managing patient symptoms during the last week on hospice had higher caregiver burden, lower caregiver satisfaction, and lower ratings of quality of EoL care.

Conclusion: Potentially modifiable symptom-related variables were correlated with caregiver-reported quality measures. Our study reinforces the important relationship between the perceived suffering/symptoms of patients and caregivers' hospice experiences.

Mobile health technology and home hospice care: promise and pitfalls

With the increasing use of mobile devices (e.g., smart phones, tablets) in our everyday lives, people have the ability to communicate and share information faster than ever before. This has led to the development of promising applications aimed at improving health and healthcare delivery for those with limited access. Hospice care, which is commonly provided at home, may particularly benefit from the use of this technology platform. This commentary outlines several potential benefits and pitfalls of incorporating mobile health (mHealth) applications into existing home hospice care while highlighting some of the relevant telemedicine work being done in the palliative and End-of-Life care fields.

Palliative Care Gaps in Providing Psychological Treatment: A Review of the Current State of Research in Multidisciplinary Palliative Care

BACKGROUND

Patients with advanced illness often have high rates of psychological symptoms. Many multicomponent palliative care intervention studies have investigated the efficacy of overall symptom reduction; however, little research has focused explicitly on how interventions address psychological symptoms associated with serious illness.

METHODS

The current study reviewed 59 multicomponent palliative care intervention articles and analyzed the mental health components of palliative care interventions and their outcomes in order to better understand the current state of psychological care in palliative care.

RESULTS

The majority of articles (69.5%) did not provide any details regarding the psychological component delivered as part of the palliative care intervention. Most (54.2%) studies did not specify which provider on the team was responsible for providing the psychological intervention. Studies varied regarding the type of outcome measure utilized; multi-symptom assessment scales were used in 54.2% of studies, mental health scales were employed in 25.4%, quality of life and distress scales were used in 16.9%, and no psychological scales were reported in 28.8%. Fewer than half the studies (42.4%) documented a change in a psychological outcome.

DISCUSSION AND CONCLUSION

The majority of analyzed studies failed to describe how psychological symptoms were identified and treated, which discipline on the team provided the treatment, and whether psychological symptoms improved as a result of the intervention. Future research evaluating the effects of palliative care interventions on psychological symptoms will benefit from using reliable and valid psychological outcome measures and providing specificity regarding the psychological components of the intervention and who provides it.

The Impact of Older Parents' Pain Symptoms on Adult Children

Objective

Not only is persistent pain a debilitating health problem for older adults, it also may have negative effects on family relationships. Studies have documented the effects of pain on spouses and on parents of young children. However, research has not extended this line of inquiry to later life, and specifically to the impact of older parents' pain symptoms on adult children. This study addresses the question: Does older mothers' pain affect the quality of relations with offspring?

Subjects and Design

Using data from a survey of 678 adult children of older mothers, this article presents two analyses examining the impact of mothers' self-reported pain on emotional closeness and on tension in the adult child-parent relationship.

Results

Contrary to research conducted on younger families, multilevel models showed no effects on emotional closeness or tension in relationships with adult children when mothers experienced higher levels of persistent pain. This surprising finding suggests that mechanisms may exist that protect adult child caregivers from stressors that result from a relative's chronic pain.

Conclusions

Based on the findings of this article, further exploration of the impact of chronic pain on relations between adult children and their parents is justified. Of interest is exploration of factors that may insulate later-life intergenerational relationships from the effects of pain.

Risk Factors for Hospitalization of Home Hospice Enrollees Development and Validation of a Predictive Tool

BACKGROUND

Over 10% of hospice patients experience at least 1 care transition 6 months prior to death. Transitions at the end of life, particularly from hospice to hospital, result in burdensome and fragmented care for patients and families. Little is known about factors that predict hospitalization in this population.

OBJECTIVES

To develop and validate a model predictive of hospitalization after enrollment into home hospice using prehospice admission risk factors.

DESIGN

Retrospective cohort study using Medicare fee-for-service claims.

PARTICIPANTS

Patients enrolled into the Medicare hospice benefit were ≥18 years old in 2012.

OUTCOME MEASURED

Hospitalization within 2 days from a hospice discharge.

RESULTS

We developed a predictive model using 61 947 hospice enrollments, of which 3347 (5.4%) underwent a hospitalization. Seven variables were associated with hospitalization: age 18 to 55 years old (adjusted odds ratio [95% confidence interval]: 2.94 [2.41-3.59]), black race (2.13 [1.93-2.34]), east region (1.97 [1.73-2.24]), a noncancer diagnosis (1.32 [1.21-1.45]), 4 or more chronic conditions (8.11 [7.19-9.14]), 2 or more prior hospice enrollments (1.75 [1.35-2.26]), and enrollment in a not-for-profit hospice (2.01 [1.86-2.18]). A risk scoring tool ranging from 0 to 29 was developed, and a cutoff score of 18 identified hospitalized patients with a positive predictive value of 22%.

CONCLUSIONS

Reasons for hospitalization among home hospice patients are complex. Patients who are younger, belong to a minority group, and have a greater number of chronic conditions are at increased odds of hospitalization. Our newly developed predictive tool identifies patients at risk for hospitalization and can serve as a benchmark for future model development.

Examining the Role of Primary Care Physicians and Challenges Faced When Their Patients Transition to Home Hospice Care

BACKGROUND

The transition into home hospice care is often a critical time in a patient's medical care. Studies have shown patients and caregivers desire continuity with their physicians at the end of life (EoL). However, it is unclear what roles primary care physicians (PCPs) play and what challenges they face caring for patients transitioning into home hospice care.

OBJECTIVES

To understand PCPs' experiences, challenges, and preferences when their patients transition to home hospice care.

DESIGN

Nineteen semi-structured phone interviews with PCPs were conducted. Study data were analyzed using standard qualitative methods.

PARTICIPANTS

Participants included PCPs from 3 academic group practices in New York City. Measured: Physician recordings were transcribed and analyzed using content analysis.

RESULTS

Most PCPs noted that there was a discrepancy between their actual role and ideal role when their patients transitioned to home hospice care. Primary care physicians expressed a desire to maintain continuity, provide psychosocial support, and collaborate actively with the hospice team. Better establishment of roles, more frequent communication with the hospice team, and use of technology to communicate with patients were mentioned as possible ways to help PCPs achieve their ideal role caring for their patients receiving home hospice care.

CONCLUSIONS

Primary care physicians expressed varying degrees of involvement during a patient's transition to home hospice care, but many desired to be more involved in their patient's care. As with patients, physicians desire to maintain continuity with their patients at the EoL and solutions to improve communication between PCPs, hospice providers, and patients need to be explored.

Awareness and Misperceptions of Hospice and Palliative Care: A Population-Based Survey Study

BACKGROUND

Despite the documented benefits of palliative and hospice care on improving patients' quality of life, these services remain underutilized. Multiple factors limit the utilization of these services, including patients' and caregivers' lack of knowledge and misperceptions.

OBJECTIVES

To examine palliative and hospice care awareness, misperceptions, and receptivity among community-dwelling adults.

DESIGN

Cross-sectional study.

SUBJECTS

New York State residents ≥18 years old who participated in the 2016 Empire State Poll.

OUTCOMES MEASURED

Palliative and hospice care awareness, misperceptions, and receptivity.

RESULTS

Of the 800 participants, 664 (83%) and 216 (27%) provided a definition of hospice care and palliative care, respectively. Of those who defined hospice care, 399 (60%) associated it with end-of-life care, 89 (13.4%) mentioned it was comfort care, and 35 (5.3%) reported hospice care provides care to patients and families. Of those who defined palliative care (n = 216), 57 (26.4%) mentioned it provided symptom management to patients, 47 (21.9%) stated it was comfort care, and 19 (8.8%) reported it was applicable in any course of an illness. Of those who defined hospice or palliative care, 248 (37.3%) had a misperception about hospice care and 115 (53.2%) had a misperception about palliative care.

CONCLUSIONS

Most community-dwelling adults did not mention the major components of palliative and hospice care in their definitions, implying a low level of awareness of these services, and misinformation is common among community-dwelling adults. Palliative and hospice care education initiatives are needed to both increase awareness of and reduce misperceptions about these services.

Practice-Based Research Priorities for Palliative Care: Results From a Research-to-Practice Consensus Workshop

We employed the research-to-practice consensus workshop (RTP; workshops held in New York City and Tompkins County, New York, in 2013) model to merge researcher and practitioner views of translational research priorities in palliative care. In the RTP approach, a diverse group of frontline providers generates a research agenda for palliative care in collaboration with researchers. We have presented the major workshop recommendations and contrasted the practice-based research priorities with those of previous consensus efforts. We uncovered notable differences and found that the RTP model can produce unique insights into research priorities. Integrating practitioner-identified needs into research priorities for palliative care can contribute to addressing palliative care more effectively as a public health issue.

Integration of geriatric mental health screening into a primary care practice: a patient satisfaction survey

OBJECTIVE

Colocation of mental health screening, assessment, and treatment in primary care reduces stigma, improves access, and increases coordination of care between mental health and primary care providers. However, little information exists regarding older adults' attitudes about screening for mental health problems in primary care. The objective of this study was to evaluate older primary care patients' acceptance of and satisfaction with screening for depression and anxiety.

METHODS

The study was conducted at an urban, academically affiliated primary care practice serving older adults. Study patients (N = 107) were screened for depression/anxiety and underwent a post-screening survey/interview to assess their reactions to the screening experience.

RESULTS

Most patients (88.6%) found the length of the screening to be "just right." A majority found the screening questions somewhat or very acceptable (73.4%) and not at all difficult (81.9%). Most participants did not find the questions stressful (84.9%) or intrusive (91.5%); and a majority were not at all embarrassed (93.4%), upset (93.4%), or uncomfortable (88.8%) during the screening process. When asked about frequency of screening, most patients (72.4%) desired screening for depression/anxiety yearly or more. Of the 79 patients who had spoken with their physicians about mental health during the visit, 89.8% reported that it was easy or very easy to talk with their physicians about depression/anxiety. Multivariate results showed that patients with higher anxiety had a lower positive reaction to the screen when controlling for gender, age, and patient-physician communication.

CONCLUSIONS

These results demonstrate strong patient support for depression and anxiety screening in primary care.

Identifying Key Priorities for Future Palliative Care Research Using an Innovative Analytic Approach

Using an innovative approach, we identified research priorities in palliative care to guide future research initiatives. We searched 7 databases (2005-2012) for review articles published on the topics of palliative and hospice-end-of-life care. The identified research recommendations (n = 648) fell into 2 distinct categories: (1) ways to improve methodological approaches and (2) specific topic areas in need of future study. The most commonly cited priority within the theme of methodological approaches was the need for enhanced rigor. Specific topics in need of future study included perspectives and needs of patients, relatives, and providers; underrepresented populations; decision-making; cost-effectiveness; provider education; spirituality; service use; and interdisciplinary approaches to delivering palliative care. This review underscores the need for additional research on specific topics and methodologically rigorous research to inform health policy and practice.

Assessing the role of cognition prior to transcatheter aortic valve replacement

Transcatheter aortic valve replacement offers patients with severe aortic stenosis an opportunity to live longer and better lives. Although this procedure allows clinicians to treat sicker and frailer patients who cannot undergo open heart surgery, age-related comorbidities, specifically cognitive impairment, must factor into the evaluation process.

Chronic pain perspectives: Managing chronic pain in older adults: 6 steps to overcoming medication barriers

These practical tips will help improve the likelihood of a successful analgesic trial in patients 65 and older.

Chronic pain and parent-child relations in later life: An important, but understudied issue

Chronic pain is a debilitating and pervasive health problem, particularly among older adults. Researchers and clinicians acknowledge that pain conditions do not occur in isolation, but rather exact a toll on the individual sufferer and the family system at large. No research, however, has explicitly explored the impact of older parents' chronic pain symptoms on their adult children. In this article, we present relevant predictions from theoretical models that identify the interpersonal effects of chronic illness and pain on family relationships. Guided by theory and empirical research on these topics, we present a conceptual framework of hypothesized risk factors for adult children of parents with chronic pain. We conclude by offering an agenda for future research.

Tailoring evidence-based interventions for new populations: a method for program adaptation through community engagement

Evidence-based interventions (EBIs) are an important tool for community health practitioners, but there is often a mismatch between the population in which the EBI was validated and the target population in which it will be used. Methods of planned adaptation identify differences in the new target population and attempt to make changes to the EBI that accommodate these differences without diluting the program's effectiveness. This article outlines an innovative method for eliciting ideas for program modifications and deciding on program changes. The Method for Program Adaptation through Community Engagement (M-PACE) uses systematic and detailed feedback from program participants to guide adaptation. The authors describe procedures for obtaining high-quality participant feedback and adjudicating recommendations to decide on program changes. M-PACE was developed as part of the adaptation of an evidence-based, arthritis self-management program for older adults. The application and results of the M-PACE method are presented using this case as an example.

Postoperative delirium in elderly patients after elective hip or knee arthroplasty performed under regional anesthesia

Delirium is a major adverse postoperative event in elderly patients. Incidence rates of postoperative delirium are difficult to determine. Because of the accuracy, brevity, and ease of use by clinical interviewers, the Confusion Assessment Method (CAM) has become widely used. This study used the CAM to determine the rate of postoperative delirium in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures under regional anesthesia. Following Institutional Review Board approval, a prospective study of 20 patients per group ages 70 and above undergoing unilateral THA or TKA was initiated. Both groups received a combined spinal-epidural, postoperative patient-controlled epidural anesthesia, and postoperative oral opioids. Patient interviews occurred five times: once preoperatively and two times each on postoperative days 1 and 2. Only two patients were assessed as delirious according to the CAM method (one in each group; 5%). Patient assessment by other clinicians indicated that five additional patients experienced acute change in mental status; however, these patients were not delirious at the times of the study interviews. The rate of delirium in the elderly after arthroplasty performed under regional anesthesia is very low. Reasons for this include patient selection criteria and anesthesia type. The study excluded patients with several proposed risk factors for postoperative delirium: prior history of dementia, history of mental illness, and use of benzodiazepines. The use of regional anesthesia may have also reduced the occurrence of postoperative delirium.

A comparison of the arthritis foundation self-help program across three race/ethnicity groups

OBJECTIVE

Despite high prevalence rates of pain among older adults, relatively few studies have examined the impact of the Arthritis Foundation Self-Help Program (ASHP) in this age group, particularly older minority groups.

DESIGN

This study compared the effects of the ASHP on groups of Hispanic, African American and non-Hispanic White older adults.

SETTING

Three senior centers in New York City.

PARTICIPANTS

Data are presented for 112 (37 African American, 38 Hispanic and 37 non-Hispanic White) participants (mean age= 75 years) age 60 and over with diverse noncancer pain disorders.

INTERVENTION

Participants enrolled in the 6-week Arthritis Self Help Course.

MAIN OUTCOME MEASURES

Participants were surveyed before and after course completion (in person) and at 18 weeks (by telephone). Demographic and clinical data were collected at baseline; outcomes included pain, mood, self-efficacy, and number of days per week spent exercising.

RESULTS

All three groups experienced significant decreases in pain intensity (P< or =.05). Significant improvements were also found in mood scores for non-Hispanic White (P=.01) and Hispanic participants (P=.03). Hispanic participants also evidenced significant improvement in their confidence to self-manage pain (P=.003) and reported fewer arthritis-related symptoms (P=.02). All three race/ethnicity groups reported substantial increases in the number of days spent doing stretching, endurance and relaxation exercises (P< or =.01).

CONCLUSION

Positive results were noted for all three race/ethnicity groups, particularly in the areas of pain reduction and uptake of stretching, endurance and relaxation exercises. Our findings support efforts to disseminate broadly the ASHP in community settings that serve older African American, Hispanic and non-Hispanic white adults.

Environmental volunteering and health outcomes over a 20-year period

PURPOSE

This study tested the hypothesis that volunteering in environmental organizations in midlife is associated with greater physical activity and improved mental and physical health over a 20-year period.

DESIGN AND METHODS

The study used data from two waves (1974 and 1994) of the Alameda County Study, a longitudinal study of health and mortality that has followed a cohort of 6,928 adults since 1965. Using logistic and multiple regression models, we examined the prospective association between environmental and other volunteerism and three outcomes (physical activity, self-reported health, and depression), with 1974 volunteerism predicting 1994 outcomes, controlling for a number of relevant covariates.

RESULTS

Midlife environmental volunteering was significantly associated with physical activity, self-reported health, and depressive symptoms.

IMPLICATIONS

This population-based study offers the first epidemiological evidence for a significant positive relationship between environmental volunteering and health and well-being outcomes. Further research, including intervention studies, is needed to confirm and shed additional light on these initial findings.

Preparing to implement a self-management program for back pain in new york city senior centers: what do prospective consumers think?

OBJECTIVE

Prior to testing the feasibility/potential efficacy of a newly developed self-management pain program for seniors with back pain, this study sought to: 1) determine prospective consumers' prior exposure to self-management pain programs, 2) determine their willingness to participate in the new program, and 3) ascertain perceived barriers/facilitators to program participation.

DESIGN

Cross-sectional survey.

SETTING

Six senior centers located in New York City.

PARTICIPANTS

We enrolled a race/ethnicity stratified (African American, Hispanic, or non-Hispanic White) sample of 90 subjects who were ages 60 years or older and had chronic back pain.

RESULTS

While 60% of non-Hispanic Whites reported prior participation in a self-management pain program, fewer Hispanic (23%) and African Americans (20%) participants reported prior participation. Most participants (80%) were strongly willing to participate in the new program. Multivariate analyses revealed that only pain intensity had a trend toward significance (P = 0.07), with higher pain scores associated with greater willingness to participate. Few barriers to participation were identified, however, respondents felt that tailoring the course to best meet the needs of those with physical disabilities, providing flexibility in class timing, and informing individuals about program benefits prior to enrollment could help maximize program reach. No race/ethnicity differences were identified with respect to willingness to participate or program participation barriers.

CONCLUSIONS

These data support efforts to disseminate self-management pain programs in older populations, particularly minority communities. The recommendations made by participants can help to guide implementation efforts of the newly developed pain program and may help to enhance both their reach and success.

A Community-Based Participatory Critique of Social Isolation Intervention Research for Community-Dwelling Older Adults

This article examines the dialogue that occurred within the structure of a Research-to-Practice Consensus Workshop that critiqued academic research priorities regarding social isolation among community-dwelling older adults and identified practice-based suggestions for a social isolation research agenda. The investigators adapted the scientific consensus workshop model to include expert practitioners and researchers in a discussion of the current state and future directions of social isolation intervention research. The group's critique resulted in several key recommendations for future research including the need for a social isolation measure with specific capacity to identify isolated older adults during a community crisis. This study demonstrates that the Research-to-Practice Consensus Workshop model can be used successfully to identify priority areas for research that have implications for community practice, construct an evidence base more relevant for community application, strengthen existing community-researcher partnerships, and build agency and practitioner capacity to take part in community-based participatory research.

The association of sexual trauma with persistent pain in a sample of women veterans receiving primary care

BACKGROUND

Women veterans report high rates of persistent pain and high rates of sexual trauma. We sought to determine whether the presence and intensity of persistent pain, as well as level of pain-related interference, in the VA Connecticut Women's Clinic population was positively associated with reports of sexual trauma.

METHODS

Women presenting for routine appointments at the VA Connecticut Women's Health Center were recruited for study. Participants (N = 213) provided detailed information about their demographic, psychosocial, clinical, pain, and sexual trauma status. Bivariate and multivariate analyses were conducted to determine whether a report of sexual trauma was independently associated with the presence of pain, and levels of pain intensity and pain-related interference.

RESULTS

A substantial majority (78%) reported an ongoing pain problem, whereas the prevalence of any reported sexual trauma was 36%. In bivariate analysis, persistent pain was associated with a greater number of chronic conditions (P < 0.01), depression symptom severity (P < 0.05), a history of military sexual harassment (P < 0.05), and military forced sex (P < 0.05). In a multivariate logistic regression analysis, persistent pain was independently associated with having at least two (OR 3.32, 95% CI 1.11, 9.90), or three or more chronic conditions (OR 7.56, 95% CI 2.34, 24.4) and depressive symptom severity score (OR 1.10, 95% CI 1.02, 1.19), but was not associated with sexual trauma (OR 1.70, 95% CI 0.66, 4.42). In multivariate linear regression analyses that included only those who reported pain at the time of the assessment, white race (P < 0.05) and sexual trauma histories (P < 0.05) were significantly associated with level of pain intensity, whereas being married (P < 0.01) was negatively associated with pain intensity. Depressive symptom score (P < 0.001) and sexual trauma (P < 0.05) were also significantly associated with level of pain interference.

CONCLUSIONS

Reported sexual trauma is prevalent and while not independently associated with the presence of pain among women veterans in our study, for those who have pain, it is associated with greater pain intensity and pain-related interference.

Sex after seventy: a pilot study of sexual function in older persons

INTRODUCTION

Limited information is available regarding sexual functioning among adults aged 70 years and older.

AIMS

To assess sexual functioning among older men and women, and ascertain patient-physician communication patterns about sexual functioning.

METHODS

Prospective participants were approached prior to scheduled appointments with their primary care physician. In-depth sexual histories were obtained along with data on their demographic, medical, psychological, and cognitive status.

MAIN OUTCOME MEASURES

Sexual functioning was assessed using standardized questionnaires, and simple yes/no questions were administered to ascertain information regarding patient-physician communication practices about sex.

RESULTS

Of the 74 eligible patients approached, 50 (68%) participated. The participants had a mean age +/- standard deviation (SD) of 81 +/- 6 years and most (56%) were women. Eighteen percent of the women and 41% of the men were sexually active. The most commonly reported sexual activity was intercourse for men and masturbation for women. Among the women, the most commonly cited reason for being sexually inactive was "no desire," whereas for most men, it was "erectile dysfunction." Sexual function scores for women were low across each category (lubrication, desire, orgasm, arousal, pain, and satisfaction.) For men, low sexual function scores were found in the domains of erectile function, orgasm, and overall satisfaction, but not desire. Only 4% of the women (vs. 36% of men) reported initiating a discussion about sexual function with their physician in the past year, whereas 7% of the women (vs. 32% of men) reported that their physician inquired about the topic in the preceding year. Finally, 32% of the women (vs. 86% of men) felt that physicians should initiate discussions about sexual function.

CONCLUSION

In this study of older adults, a minority reported current sexual activity. Among sexually inactive women, most did not wish to resume activity, whereas desire for sexual activity remained high among men, despite substantial problems with erectile dysfunction.

Severe deficiencies of IGF-I, IGF-II, IGFBP-3, ALS and paradoxically high-normal bone mass in a child with insulin-resistance syndrome (Rabson-Mendenhall type)

Rabson-Mendenhall syndrome is a rare genetic disorder characterized by severe insulin resistance and hyperinsulinemia due to defects in signaling through the insulin receptor. Herein, we describe a new case of Rabson-Mendenhall syndrome in which investigations of the growth hormone (GH) - insulin-like growth factor (IGF) axis - reveal severe deficiencies in total and free insulin-like growth factor-I (IGF-I), IGF-II, IGF-binding protein-3 (IGFBP-3), and the acid labile subunit (ALS). Based on these findings, we anticipated significant bone deficits, as have been described in other clinical scenarios in which the IGF axis is significantly perturbed. Long-bone studies revealed no gross malformations. Paradoxically, DXA scanning revealed a total body bone density Z-score of +2.0 (0.8 gm/cm(2)), suggesting an overall high-normal BMD for age and a high BMD corrected for bone or height age. The mechanisms by which BMD is protected from severe deficiencies in the IGF-axis are unknown, yet may involve enhanced IGF sensitivity, increased local production of IGFs, and/or supra-physiological concentrations of insulin substituting for the actions of IGFs in bone.

Can hip protector use in the nursing home be predicted?

OBJECTIVES

To identify resident- and caregiver-related factors that influence hip protector (HP) usage.

DESIGN

Prospective observational cohort study over 6 weeks.

SETTING

A 409-bed nursing home located in New York City.

PARTICIPANTS

Fifty-two residents and 60 certified nursing assistants (CNAs).

INTERVENTION

Free HPs were provided to residents enrolled in the study.

MEASUREMENTS

HP adherence (number of hours HPs were worn/shift); HP users (subjects who used HPs for more than 1 hour during any 8-hour shift as recorded by CNAs in week 6 or who used HPs at checks performed by research staff in week 6 and intended future use); CNAs' scores on a questionnaire quantifying osteoporosis knowledge, opinions on HPs, job satisfaction, and health locus of control.

RESULTS

Sixty-eight percent of residents were HP users. Factors independently associated with this outcome included male sex, age, Parkinson's disease, family involvement, impaired cognition, dependent ambulation, and CNAs' sense that chance affects health outcomes. In multivariate models, anxiety, resistive behaviors, ambulation, and fall history in residents and CNAs' perceptions of HPs and their sense of how chance or other staff determine health outcomes predicted HP adherence.

CONCLUSION

Resident-related factors and CNAs' sense of external controls predicted HP users and HP adherence. CNAs' understanding of osteoporosis and HP affected only HP adherence. Most resident-related factors were not remediable but might help to target likely HP users. To improve HP adherence, educational programs should be designed to improve CNAs' understanding of osteoporosis and HP. Larger studies are needed to confirm these findings.

Completing an advance directive in the primary care setting: what do we need for success?

OBJECTIVES

To systematically review studies designed to increase advance directive completion in the primary care setting and employ meta-analytic techniques to quantify their effects.

DESIGN

Extensive bibliographic searches of English-language literature published from January 1991 through July 2005 were conducted. Investigators abstracted prespecified information (e.g., design, study duration, types of interventions employed) and advance directive completion rates for intervention and control arms in each investigation and calculated absolute rate differences (i.e., difference in completion rates between the two groups) for each study. Individual study and pooled-effect sizes were also calculated, along with 95% confidence intervals (CIs).

SETTING

Literature review.

RESULTS

Eighteen studies were retained in the final sample. Most studies employed multimodal interventions. The most common approach consisted of educational materials directed at patients (through mailing or at visit) coupled with a patient-healthcare provider interaction in a group or individual setting (n=7). Absolute differences in completion rates varied from a high of 44% (favors intervention) to a low of -2% (favors control). Effect sizes could be calculated for 15 of the 18 studies. The pooled effect size was 0.50 (95% CI=0.17-0.83), indicating a moderate overall effect in favor of the intervention.

CONCLUSION

The majority of studies demonstrated statistically significant effects associated with the advance directive intervention. The most successful interventions incorporated direct patient-healthcare professional interactions over multiple visits. Passive education of patients using written materials (without direct counseling) was a relatively ineffective method for increasing advance directive completion rates in the primary care setting.

Light to moderate alcohol consumption is associated with better cognitive function among older male veterans receiving primary care

Among older persons, the effects of light to moderate alcohol consumption on cognitive function remain inadequately defined. The authors sought to determine whether light to moderate drinking is associated with better cognitive function among older men. Participants included men aged 65 years or older enrolled in a Veteran's Administration (VA) primary care clinic. Current (past 1 year) and lifetime use, cognitive functioning (as determined by the Trail Making Part B, Symbol Digit, FAS, and Hopkins Verbal Learning tests), and demographic, psychosocial, and medical status were obtained using standardized methods. Participants (N = 760) had a mean age of 74 (range, 65-89) years. Current drinkers (n = 509) as compared with never (n = 31) and former (n = 220) drinkers demonstrated significantly better cognitive performance on 3 (Trails B, Symbol Digit, and Hopkins Verbal Learning) of the 4 tests (P < .01 for all comparisons). In multiple linear regression models, current light to moderate drinking (ie, 7 or fewer drinks per week), as compared to a reference group of never and former drinkers, was associated with better performance on the Trails B, Symbol Digit, and Hopkins Verbal Learning tests (P < .01 for all comparisons). The number of years drinking 7 or fewer drinks per week also was independently associated with better cognitive performance. Current consumption of 7 or fewer drinks per week and the number of years drinking at this level are both associated with better cognitive performance in older male veterans receiving primary care. These findings are consistent with the hypothesis that light to moderate drinking confers cognitive benefits to older persons.

Are Commonly Ordered Lab Tests Useful Screens for Alcohol Disorders in Older Male Veterans Receiving Primary Care?

Although mean corpuscular volume (MCV), aspartate aminotransferase (AST), alanine aminotransferases (ALT), and the AST/ALT ratio are sometimes used as markers of alcohol disorders, their utility has not been established in older persons. We determined the tests' performance characteristics for (1) at-risk drinking, (2) CAGE positivity, (3) at-risk drinking and CAGE positivity, and (4) a clinician-recorded diagnosis of alcohol abuse/dependence in a study of older male veterans receiving primary care. Participants (n = 587) included patients who had MCV, AST, and/or ALT data collected as part of routine care no more than 12 weeks before or after enrollment. MCV, AST, and ALT test results were obtained from the VA's database. At enrollment, the Timeline Followback and Alcohol Use Disorders Identification Test (AUDIT) were used to identify at-risk drinkers (> or = 15 drinks per week or AUDIT score > or = 8), and the CAGE questionnaire was administered to identify participants with a history abuse/dependent drinking (CAGE score > or = 2). Participants' medical records were reviewed to identify subjects with a clinician-recorded diagnosis of alcohol abuse/dependence. The prevalence of abnormal test results for MCV (threshold value = > 98), AST (> 41), ALT (> 41), and the AST/ALT ratio (> 2) was 11%, 4%, 4%, and 5%, respectively. The occurrence of at-risk drinking, CAGE positivity, at-risk drinking and CAGE positivity, and a clinician-recorded diagnosis of alcohol abuse/dependence was 11%, 25%, 5%, and 9%, respectively. Test sensitivity ranged from 3.9% to 25.4% and specificity from 88.5% to 97.1%, whereas positive likelihood ratios varied from 0.72 to 4.01 and negative likelihood ratios from 0.82 to 1.04. Areas under the receiver operating characteristic curve were similar (range = 0.50-0.58) across tests. In conclusion, MCV, AST, ALT, and the AST/ALT ratio are not useful markers of alcohol disorders in older male veterans.

Properties and substrate of slow pathway exposed with a compact node targeted fast pathway ablation in rabbit atrioventricular node

INTRODUCTION

The properties and substrates of slow and fast AV nodal pathway remain unclear. This applies particularly to the slow pathway (SP), which is largely concealed by fast pathway (FP) conduction. We designed a new FP ablation approach that exposes the SP over the entire cycle length range and allows for its independent characterization and ablation.

METHODS AND RESULTS

Premature stimulation was performed before and after FP ablation with 5.4 +/- 1.9 lesions (300-microm diameter each; overall lesion size 1.4 +/- 0.5 mm) targeting the junction between perinodal and compact node tissues in seven rabbit heart preparations. The resulting SP recovery curve and control curve had the same maximum nodal conduction time (165 +/- 22 msec vs 164 +/- 24 msec; P = NS) and effective refractory period (101 +/- 10 msec vs 100 +/- 9 msec; P = NS). The two curves covered the same cycle length range. However, the SP curve was shifted up with respect to control one at intermediate and long cycle lengths and thus showed a longer minimum nodal conduction time (81 +/- 15 msec vs 66 +/- 10 msec; P < 0.01) and functional refractory period (180 +/- 11 msec vs 170 +/- 12 msec; P < 0.05). The SP curve was continuous and closely fitted by a single exponential function. Small local lesions (2 +/- 1) applied to the posterior nodal extension resulted in third-degree nodal block in all preparations.

CONCLUSION

The posterior nodal extension can sustain effective atrial-His conduction at all cycle lengths and account for both the manifest and concealed portion of SP. Slow and FP conduction primarily arise from the posterior extension and compact node, respectively.

Exercise tolerance and quality of life in elderly patients with chronic atrial fibrillation

BACKGROUND

Atrial fibrillation is the most common arrhythmia affecting the elderly. Although the risk of cardioembolic stroke is well defined, the effects of chronic atrial fibrillation on exercise tolerance and quality of life have been less well quantified.

METHODS

We compared a group of 52 elderly patients with chronic atrial fibrillation to a group of 48 control patients in sinus rhythm. Each patient underwent an interview that incorporated the Short Form-36 Health Survey (SF-36) to quantify individual perceptions on quality of life. In addition each person underwent physiologic testing that included a Modified Bruce Protocol exercise tolerance test, 24-hour ambulatory monitor test, and an echocardiogram.

RESULTS

Both groups were elderly, 77 vs 76 years of age (P=0.35). The two groups had similar ejection fractions, 55.4% vs 58.4% (P=0.10). The atrial fibrillation patients demonstrated a higher level of comorbidity based on the Charlson Comorbidity Index, 2.46 vs 1.57 (P=0.03). On formal exercise testing there was no statistical difference in exercise duration between the two groups 9.0 vs 10.1 minutes (P=0.24). Similarly the Physical Summary Score (PCS) and the Mental Summary Score (MCS) of the SF-36 quality of life survey did not demonstrate a statistical difference between the two groups. PCS: 43.0 vs 45.9 (P=0.24);

MCS

52.5 vs 55.7 (P=0.07).

CONCLUSIONS

Despite a higher level of comorbidity, elderly, ambulatory patients with chronic atrial fibrillation demonstrate similar exercise tolerance and report similar quality of life to a group of age-matched control patients in sinus rhythm. There is a cohort of patients in chronic atrial fibrillation in whom a strategy of rate control and anticoagulation may be appropriate.

Similarities in the disturbances in cortical information processing in alcoholism and aging: a pilot evoked potential study

OBJECTIVE

To examine the hypothesis that chronic alcohol use causes accelerated aging of the brain.

METHODS

The auditory evoked potentials (EPs) were compared in three groups of 10 subjects each: (a) middle-aged individuals meeting DSM-IV criteria for alcohol dependence, (b) age- and gender-matched group of healthy individuals, and (c) an older (>65 years) group of gender-matched healthy individuals. Multiple levels of cortical information processing were examined using EPs. Early stages of information processing, related to sensory gating and stimulus classification (P50, N100/P200), were studied using a paired-click paradigm. Later stages of information processing associated with memory upgrading and identification of novel stimuli (P300) were studied using an oddball paradigm.

RESULTS

The amplitude and latency of the P300 of the alcoholic patients and the older healthy subjects differed significantly from those of the younger healthy group. Both groups showed changes that have been reported in association with aging. A tendency towards decreased sensory gating in later stages of information processing was noted in the aged healthy individuals.

CONCLUSIONS

These data suggest that alcohol dependence may accelerate the aging process. The tendency towards a sensory gating deficit during the attentive phase of information processing in older healthy subjects requires further investigation because it may be a marker for an increased proneness to developing psychotic symptoms in that group.

Outpatient management of patients with alcohol problems

This paper addresses the clinical presentation of patients with alcohol problems including screening, diagnosis, detoxification, treatment, referral, and longitudinal follow-up. The case-based discussion focuses on the clinical management of a patient whose hazardous drinking progresses to alcohol dependence and requires coordinated care. Ways in which internists can aid patients with alcohol problems by screening, giving brief advice, and providing appropriate referrals when indicated are discussed.

Screening for alcohol problems in primary care: a systematic review

BACKGROUND

Primary care physicians can play a unique role in recognizing and treating patients with alcohol problems.

OBJECTIVE

To evaluate the accuracy of screening methods for alcohol problems in primary care.

METHODS

We performed a search of MEDLINE for years 1966 through 1998. We included studies that were in English, were performed in primary care, and reported the performance characteristics of screening methods for alcohol problems against a criterion standard. Two reviewers appraised all articles for methodological content and results.

RESULTS

Thirty-eight studies were identified. Eleven screened for at-risk, hazardous, or harmful drinking; 27 screened for alcohol abuse and dependence. A variety of screening methods were evaluated. The Alcohol Use Disorders Identification Test (AUDIT) was most effective in identifying subjects with at-risk, hazardous, or harmful drinking (sensitivity, 51%-97%; specificity, 78%-96%), while the CAGE questions proved superior for detecting alcohol abuse and dependence (sensitivity, 43%-94%; specificity, 70%-97%). These 2 formal screening instruments consistently performed better than other methods, including quantity-frequency questions. The studies inconsistently adhered to methodological standards for diagnostic test research: 3 (8%) provided a full description of patient spectrum (demographics and comorbidity), 30 (79%) avoided workup bias, 12 (of 34 studies [35%]) avoided review bias, and 21 (55%) performed an analysis in pertinent clinical subgroups.

CONCLUSIONS

Despite methodological limitations, the literature supports the use of formal screening instruments over other clinical measures to increase the recognition of alcohol problems in primary care. Future research in this field will benefit from increased adherence to methodological standards for diagnostic tests.

New therapies for alcohol problems: application to primary care

Primary care physicians are frequently involved in the longitudinal care of patients with alcohol problems and in helping patients to decrease their alcohol consumption. Recent clinical trials provide evidence in support of new treatment strategies for these patients. Brief interventions have been used successfully to reduce alcohol consumption in patients with hazardous and harmful drinking. Twelve-step facilitation, cognitive behavioral, and motivational enhancement therapies have produced sustained drinking reductions in patients with alcohol dependence. Pharmacologic therapies, such as naltrexone and acamprosate, have been effective in decreasing alcohol consumption when provided along with psychosocial counseling in patients with alcohol dependence. The current review highlights the application of these new therapies to primary care physicians' efforts on behalf of their patients with alcohol problems.

Alcohol exposure and health services utilization in older veterans

The objective of this study was to determine if increased alcohol exposure is associated with greater use of health services among older veterans. A total of 129 older veterans (> or =65 years old), receiving longitudinal care in a Veterans' Administration primary care clinic, were followed retrospectively for up to 42 months. Subjects were screened at baseline for problem drinking with the CAGE or the quantity-frequency questions from the Alcohol Use Disorders Identification Test (QF-AUDIT), and stratified by exposure into three categories: abstainers, social drinkers, and problem drinkers. Outcomes included total outpatient clinic visits, laboratory tests, radiologic and other technologic procedures, as well as acute care hospitalizations. For all subjects (N = 129), no association was found between alcohol exposure and use of any outpatient services. Among CAGE-screened (n = 62) abstainers, social drinkers, and problem drinkers, significant differences were found in the median number of laboratory tests (7.3 vs. 3.4 vs. 7.1, P = 0.004) and hospitalizations (0.3 vs. 0.0 vs. 0.3, P = 0.001) per patient year of follow-up. No exposure-outcome associations were present, however, among QF-AUDIT-screened subjects (n = 67). We were unable to demonstrate a consistent relationship between alcohol exposure and health services utilization. The effects of alcohol on older veterans' use of health services varied with the method used to measure alcohol exposure. Additional studies are needed to determine whether multiple, or possibly new, measures can more precisely define the health effects of alcohol in older populations.

Hazardous and harmful alcohol consumption in primary care

Increasing emphasis has been placed on the detection and treatment of hazardous and harmful drinking disorders, particularly among patients who are seen in primary care settings. In this review, we summarize the epidemiology and health-related effects of hazardous and harmful drinking and discuss current methods for their detection and treatment. Hazardous drinking is defined as a quantity or pattern of alcohol consumption that places patients at risk for adverse health events, while harmful drinking is defined as alcohol consumption that results in adverse events (e.g., physical or psychological harm). Prevalence estimates range from 4% to 29% for hazardous drinking and from less than 1% to 10% for harmful drinking. Data from several recent large prospective studies suggest that alcohol consumption in quantities consistent with hazardous or harmful drinking may increase risk for adverse health events, such as hemorrhagic stroke and breast cancer. Existing screening instruments, such as the Michigan Alcoholism Screening Test (MAST) or the CAGE questionnaire, while excellent for detecting alcohol abuse or dependence, should not be used alone to screen for hazardous and harmful drinking. The Alcohol Use Disorders Identification Test (AUDIT) is currently the only instrument specifically designed to identify hazardous and harmful drinking. Treatment of these disorders in the form of brief interventions can be successfully accomplished in primary care settings, as demonstrated by a number of well-conducted randomized trials. Given its proven efficacy in the primary care setting, we recommend routine application of this treatment approach.

Alcohol use and functional disability among cognitively impaired adults

BACKGROUND

The extent to which alcohol exposure increases risk for functional disability among older adults with cognitive impairment has not previously been assessed.

OBJECTIVE

To examine the potential relationship between alcohol use and functional disability among older cognitively impaired adults.

DESIGN

Retrospective medical record review.

SETTING

Hospital-based geriatric assessment center.

PARTICIPANTS

Two hundred forty-two consecutive participants with Mini-Mental Status Examination scores of < or = 24.

MEASUREMENTS

Proxy-reported alcohol intake was classified in categories of never, former, light (< 1 drink/week), moderate (> or = 1 but < 14 drinks/week), and heavy (> or = 14 drinks/week) drinkers, and functional status was determined by proxy-reported performance in seven basic (BADL) and seven instrumental (IADL) activities of daily living (0 = poorest function and 14 = best function).

RESULTS

Compared with never drinkers, moderate drinkers demonstrated higher mean BADL (12.2 vs 11.4, P = .033) and IADL scores (6.6 vs 5.6, P = .067), whereas heavy drinkers had higher BADL (12.8 vs 11.4, P = .019) but lower IADL scores (4.8 vs 5.6, P = .425). Former drinkers demonstrated both lower BADL (10.8 vs 11.4, P = .107) and IADL scores (3.9 vs 5.6, P = .011) compared with never drinkers. Evaluation of a potential dose-response effect was limited due to low numbers of light and heavy drinkers.

CONCLUSIONS

Among cognitively impaired adults, moderate and heavy drinkers demonstrated better BADL function, whereas former drinkers had poorer IADL function, compared with never drinkers. Prospective studies that incorporate additional measures of exposure (e.g., cumulative lifetime consumption) and function (e.g., performance-based tests) may provide a more comprehensive understanding of alcohol's effects among older cognitively impaired adults.

Physician awareness of alcohol use disorders among older patients

OBJECTIVES

To determine primary care physicians' awareness of, and screening practices for, alcohol use disorders (AUDs) among older patients.

DESIGN

Cross-sectional telephone survey of a national sample of primary care physicians.

PARTICIPANTS

Physicians randomly sampled from the Masterfile database of the American Medical Association and stratified by specialty as family practice physicians, internal medicine physicians, and either family practice or internal medicine physicians with geriatric certification.

MAIN RESULTS

A total of 171 physicians were contacted: 155 (91%) agreed to participate, and responses were analyzed from 150 (50 family practice, 50 internal medicine, 50 with geriatric certification). The median prevalence estimate of AUDs among older patients was 5% for each group of physicians. In contrast to published prevalence rates of AUDs ranging from 5% to 23%, 38% of physicians reported prevalence estimates of less than 5%, and 5% cited estimates of at least 25%. Compared with the other groups, the physicians with geriatric certification were more likely to report no regular screening (42% vs 20% for family practice vs 18% for internal medicine, p = .01), while younger (<40 years) and middle-aged physicians (40-55 years) reported higher annual screening rates relative to older physicians (>55 years) (77% vs 60% vs 44% respectively, p = .03). Among physicians who regularly screened (n = 110), 100% asked quantity-frequency questions, 39% also used the CAGE questions, and 15% also cited use of biochemical markers.

CONCLUSIONS

Primary care physicians may "underdetect" AUDs among older patients. The development of age-specific screening methods and physician education may facilitate detection of older patients with (or at risk for) these disorders.

Academic calculations versus clinical judgments: practicing physicians' use of quantitative measures of test accuracy

PURPOSE

To determine how often practicing physicians use the customarily recommended quantitative methods that include sensitivity, specificity, and likelihood ratio indexes; receiver operator characteristic (ROC) curves; and Bayesian diagnostic calculations.

PARTICIPANTS AND METHODS

A random sample of 300 practicing physicians (stratified by specialty to include family physicians, general internists, general surgeons, pediatricians, obstetrician/gynecologists, and internal medicine subspecialists) were briefly interviewed in a telephone survey. They were asked about the frequency with which they used the formal methods, the reasons for non-use, and if they employed alternative strategies when appraising tests' diagnostic accuracy.

RESULTS

Of the 300 surveyed physicians, 8 (3%) used the recommended formal Bayesian calculations, 3 used ROC curves, and 2 used likelihood ratios. The main reasons cited for non-use included impracticality of the Bayesian method (74%), and nonfamiliarity with ROC curves and likelihood ratios (97%). Of the 174 physicians who said they used sensitivity and specificity indexes, 165 (95%) did not do so in the recommended formal manner. Instead, the physicians directly estimated tests' diagnostic accuracy by determining how often the test results were correct in groups of patients later found to have, or to be free of, the selected disease.

CONCLUSIONS

The results indicate that most practicing physicians do not use the formal recommended quantitative methods to appraise tests' diagnostic accuracy, and instead report using an alternative direct approach. Although additional training might make physicians use the formal methods more often, the physicians' direct method merits further evaluation as a potentially pragmatic tool for the determination of tests' diagnostic accuracy in clinical practice.

The consequences of overdiagnosis and overtreatment of Lyme disease: an observational study

BACKGROUND

The adverse consequences associated with overdiagnosis and overtreatment of Lyme disease, although previously recognized, have received inadequate attention.

OBJECTIVE

To determine the use of health services and occurrence of treatment-related illness, disability, and distress among patients in whom Lyme disease is inappropriately diagnosed or treated.

DESIGN

Observational cohort study.

SETTING

University-based Lyme disease clinic.

PARTICIPANTS

209 patients with a presumptive diagnosis of Lyme disease previously assigned by referring physicians, the patients themselves, or both.

MEASUREMENTS

Self-reported data, review of medical records, and standardized instruments were used to determine 1) use of health services in terms of number of outpatient visits, number of physicians seen, types of serologic tests, and days of antibiotic treatment; 2) occurrence of antibiotic-related adverse events; and 3) levels of disability, depression, and stress.

RESULTS

Of the 209 patients, 44 (21%) met criteria for active Lyme disease, 40 (19%) had previous but not active Lyme disease, and 125 (60%) had no evidence of current or previous infection. In general, patients with active Lyme disease (who were not the focus of this study) had good outcomes. Patients with previous Lyme disease and patients with no evidence of Lyme disease used considerable health resources (median number of office visits, 11 and 7; median number of serologic tests, 4 and 4; and median days of antibiotic treatment, 75 and 42), had frequent minor adverse drug events (53% and 55%), reported significant disability (proportion of symptomatic days during which normal activities could not be performed, 16% and 18%), and had high rates of depression (38% and 42%) and stress (52% and 45%).

CONCLUSIONS

Overdiagnosis and overtreatment of Lyme disease are associated with inappropriate use of health services, avoidable treatment-related illness, and substantial disability and distress.
